Realising they weren’t going to make it to through the hospital doors, panicked husband Kris, 27, pulled up at the number two bus stop and jumped out from behind the wheel to help deliver the baby in the front passenger seat, as waiting bus passengers watched and their children – Isabella, four, and Leonardo, two – sat in the back of the car.

Kris and Lisa ignored the surprised spectators and just a few minutes after pulling over, they heard their little boy cry for the first time – along with cheers of congratulations from the watching crowd.

Barber Lisa said: “I had a miscarriage just before I fell pregnant with Luca and that was devastating. We fell pregnant a month after I stopped bleeding and I was worried all the way through the pregnancy.

“He was growing really well throughout the pregnancy but did stop growing towards the end. I’d had a scan and they said he was perfectly in proportion, which put my mind at ease but I was looking forward to him being born.

“He was our little miracle so I was just so glad to hear him cry and didn’t care that everyone queuing at the bus stop was watching.”

But, when she realised the baby was coming fast, the couple piled their children into the back of their gold Ford Mondeo car, arranging to meet the grandparents at the hospital.

“I knew when I got into the car that I wasn’t going to make it to hospital,” said Lisa. “I told my husband to pull over, because I thought the baby was going to pop out. I had one leg on the dashboard and one on the window. It wasn’t glamorous at all.”

As they pulled into the hospital car park, Lisa could feel her baby’s head.

Realising the urgency, Kris pulled up at the main hospital bus stop, rushing to help his wife.

Flinging the front passenger door open, a crowd quickly gathering to watch, Kris felt the baby’s head and Lisa gave one more push, before lifting their newborn boy onto her chest.

Sitting in the back seat, her kids watched over her shoulder and her daughter Isabella climbed out and touched her baby brother’s head as Lisa gave birth.

As they wrapped the baby boy in Lisa’s coat, her parents pulled up behind, then and two midwives arrived from the ward to help.

Lisa – who had delivered her daughter in 22 minutes after her waters were forcibly broken and had her son Leonardo in two hours – and her new baby were taken to the maternity ward, where they were both checked over.

Weighing just 5lb 10oz, baby Luca, born three weeks early, was happy and healthy and mum and baby were able to go home just five hours later.

“I sat in the back on the way home. The front seat was still wet and I refused to sit there until we got it cleaned. I think it took us three different types of cleaners to get it back to normal,” Lisa laughed.

But despite his dramatic entrance to the world, Luca is thriving and Lisa is loving being a mum again.

She said: “He is doing so well now. He’s put loads of weight on and he’s a lovely little baby, which is all that matters.”

Kris, who started dating Lisa when she was just 13 and he was 15 after meeting through school friends and married her in 2011, said: “The whole car journey was so panicked and Lisa was telling me to pull over but I didn’t have a clue about what to do.

“It was amazing being able to be there for her and help with the birth as men don’t usually get so involved.

“She was amazing the whole time and it was just one of the best moments of my life when I heard him cry and I realised that both Lisa and the baby were OK.”
